I. Standard Benchmark(s) and Learning Objective:

The learning objective is fairly clear: help children understand fractions. There are six pieces of the candy bar, and five candy bars, and they have to divide them amongst each other evenly. This requires them to split the pieces up into a multiple of so that each child gets the same amount. Fractions are used, but a real world situation is also involved. This allows the kids to relate fractions to life, and more importantly, diving food, something that no kid wants to get ripped off with. Also, the children have to convey exaclty how they found their answer, making them describe their math reasoning.


II. The Learning Environment

They are in a classroom, with desks and chairs. However, they are working in groups with the work in the center of them. This allows the children to be all facing each other and all involved in the lesson. It was bright in the room, which also helps the students stay awake and focused.

There was both teacher-students and student-student interactions during this lesson plan. The teacher-student interactions in this lesson are when the students had a question about the activiy then they would ask. Also, the teacher was walking around the room asking the students what they were doing to get thier answer. As well as having them show him what he was doing. The student-student interactions in this lesson was that they were working in groups talking among each other.


III. The Learning Activities

There are 5 pieces of brown paper representing candy bars. Each one is to be divided between the children and then they must be able to express their mathematical reasoning. They are also working in groups which is an activity in itself. They use the paper to split up the bars evenly between each other and they must present their findings to the class, helping their math, writing, social development, and presenting skills.

Most of the groups cut up the "candy bar" so it was easier for them to see how they were going to share it. By doing this, they had go figur out what 1/2 of one 1/6 was. Someof the groups figured it out right away where others had to use other things in the classroom ti figur it out.


IV. Personal Reflections (Yours)

I think that this was a very effective lesson. There was a very interesting opening which allowed the task at hand to be related to something in the children's lives. The activity was very successful because the children had to use reasoning and their social skills to determine the fractions of the candy bar. The teacher was a great facilitator. He let the students figured out the problem on their own, he just helped guide them in the right direction. One student said 1/2 of 1/6 was 1/3, and the teacher proceeded to use a visual and ask him how many pieces would be in a whole bar. The ending of the lesson, making the children present, allows the children to show that they understood the lesson and it also boosts their mathematic confidence. This was a very effective lesson becuase of its simplicity, relation to the real world, and many different skills that were polished.

I think that this lesson was very effecive in a number of different ways. One way is that the lesson was effective is that the teacher used a really life situation to help the studnets understand factions. By using something in which the students can relate to then they are going to pay more attation and learn something, where a student really is not going to care about pens and sharing them. Another way in which it is effective is that it each the children how to share. Many children do not like to share food, but by doing this lesson they learn that they need to share wiith others. The teacher did a good job in picking this lesson and they way he taught the lesson. ~Pam
